When I was in massage therapy school, two of the greatest things for assisting memory I ever fell over was the power of music to aid in memory retention, and, the power of laughter to help memory recall. Classmates would crack a joke about a topic for discussion (especially in anatomy and physiology) or, someone would sing a song that would seem appropriate to the subject matter at hand. Come testing time, remembering the music, or, the joke, always made recall of the materials so much easier
